We went to the Arnold
Arboretum. First we used microscopes to look at the Wooly Adelgid,
which is killing Hemlock Trees. A couple days later we went to the
Arboretum to see sick and healthy Hemlocks. Many of the trees are
already dead. We measured the trees to see how old they are. We used magnifying
glasses to see if there were any adelgid bugs on the trees.
We didn't get to run around, but we had some fun. We saw chipmunks and a hawk, and lots of spiders. |
